Crumble tofu in a large mixing bowl. Add enough olive oil to cover all the tofu (about 4-5 tablespoons). Add the Old Bay seasoning and the herbs. Work this with your hands for about a minute. Pour 4-5 tablespoons of olive oil in a frying pan. Add the teriaki sauce and the tahini. Bring this to a slight boil and put in the tofu. Cook for 5-10 minutes or until cooked, stirring regularly.
